A Lower East Side music producer says Kanye West and Damon Dash ripped off his trademarked “Loisaidas” band name for their new movie — and he’s furious because the flick promotes murder and drugs.

Michael Medina says in a Manhattan Federal Court suit filed Thursday that the rap moguls’ new movie about street life in the ‘hood gives his Latin duo “Loisadas” — slang for Lower East Side — a bad name.

The music group is signed to Medina’s independent music label, 848 Enterprises, and he trademarked the name in 2011, he told The Post.

“I’m disgusted that they’re taking a brand that I made and built and turning it into something that it isn’t,” said Medina, 47.

The movie,which was produced by West and Dash, premiered in New York City last month and tells a story about the hard-scrabble life of “a new breed of hustlers, The Loisaidas,” according to the flick’s Web site.

“We’re a bachata group, we do music, we do videos, we do audio,” said a frustrated Medina. “It’s not a movie based on something that happened – some street activities. That’s not what I’m promoting.”

Medina said last year he tried to approach Dash, rapper Jay-Z’s ex-business partner, about the trademark conflict as he was filming the movie. But the businessman, who still lives in the Lower East Side, was rebuffed by security.

Now, he hopes they can reach an “amicable” resolution that involves Dash and West ceasing from using the “Loisaidas” name.

“I’m not in this for a paycheck,” said Medina, “but I’m not going to let anyone use something that I worked hard for, that I’ve branded, that’s under my label.”

Reps for West and Dash didn’t immediately return messages.

Medina, who is acting as his own lawyer, is seeking unspecified damages.
